TransCanada Says Oil Leak Estimated at Keystone Pipeline May be 16,800 Gallons
On Saturday, the oil leak that was discovered on the keystone pipeline and forced a part of it to be shut down appears to be spilling more oil than expected by TransCanada initially. The company had informed regulators that the oil spill was approximately estimated to be 187 gallons. The Keystone crude oil pipeline carries 590,000 barrel oil per day and on Thursday, the company said around four hundred barrels or around 16,800 gallons could have spilled in South Dakota.
According to the company, the spill volume estimate was based on excavation that was done to expose more than hundred feet of pipe which the company is still investigating to locate the source of the oil spill.
However, according to reports, TransCanada has "made progress" in trying to locate the leaks source but has not found it yet.
In spite of that, the Calgary, Canada based company said the spill has been "controlled" as certain parts of the pipeline was immediately shut down after the leak was reported. According to the company visual inspections were done to confirm closing of the valves. TransCanada said, "There is no significant environmental impact observed."
Around hundred workers are working "around the clock" with regulators keeping a watch on the site. It lies approximately four miles from the company's Freeman pump station in Hutchinson County, South Dakota.
